I have a Canon MF8380CDW connected to my network here at my office and once a while the ip address will change on the printer. When that happens my laptop will not printer, then I have to go into printing properties and change ip address to the correct one. The other thing is I have four other desktops connected to the network and when the ip address changes on the printer those desktops all printer fine. Does anybody know what is causing this printing to the laptop but not to the desktops? Sorry if this is a little confusing. Please help if you can. Thanks!
